Let's say a blog is PR 6. Now you enter the blog. You see recent posts and you click on one to comment. It takes you to a new page with just that blog post. you comment. Does your comment count as a PR 6 or a different PR. Thank you
if you click on the 'recent posts' button it will take you to a new page and that new page will be a pr-0, especially since the google pr update wont happen for awhile. its possible that the page gains some PR but it will not have anything near the link-juice the home page would.
Your comment or Link created will have the same PR as to the page where you put it from, but do not despair even if the page in currently unranked or pr0, it will increase its PR in the near future
Different PR, normally PR N/A. It's all good though because the PR on main page flows to internal comments. Not much PR juice but juice nonetheless. You shouldn't worry about the PR of the page you're commenting on. Worry more about the number of existing comments on that page you have to split PR juice with....
when you click on comment button it will show as no pagerank but if your comment approved in same page it will get same PR.
Every page have a different PR. Thats why ppl is looking for a high PR do follow comment (a specific page/thread/post) let say this thread "showthread.php?t=1424232" have pr 4 if you put post here with your web link it will give a pr 4 link to your web.
I believe your blog will benefit by having such links from inner do follow pages. There are ton of inner pages ranked 6+ and I am sure if you provide quality comments, the blogger will let you in.
When I post comments on blog bosts I'm hoping it will gain PR in the future. I don't normally bother from an SEO point of view if I'm not in the first 10 comment posts Unless I'm on a popular blog but even then not if its got 30 plus comments already. On popular blogs I'm hoping for an actual visit from a real person which still helps SEO I think.
for checking do follow list there is a great add on name as DONOFOLLOW it will tell you whether the site is do follow or not. Thanks.
